Abstract
A method and system for increasing speeds of transferring data in a data transfer system which includes a data source and data sink. Both the data source and data sink include clocks which are synchronized to a common clock frequency. A buffer is provided at the data sink and this buffer is utilized to received data from the data source. A control circuit is provided at the data sink and this control circuit receives a bus clock signal from the data source. An N segment dynamic shift register is provided within the data sink which includes at least two segments. A selectable shift control is provided for passing the data through an M segment subset of the N segment shift register, where M is less than N. Additionally, the length of the M segment subset is determined by the phase of a clock within the data sink at the time which the bus clock signal from the data source is received at the data sink. By selectively passing the data through an M segment subset of the N segment shift register, the data is accessible at the data sink at a controllable predetermined time.
